Failed to make Restate admin API call

[krisztiansala]

I'm trying to use the RestateDeployment CRD, but I'm getting these errors.
I get this in the CRD:

failed to apply object: Failed to make Restate admin API call: HTTP status server error (500 Internal Server Error) for url (http://restate.restate.svc.cluster.local:9070/deployments)

And this one in the Restate operator:

2025-10-06T20:56:05.864516Z DEBUG reconciling object:reconcile: restate_operator::controllers::restatedeployment::reconcilers::service: Applying Service my-app-dbcbbcc758 in namespace stag object.ref=RestateDeployment.v1beta1.restate.dev/my-app.stag object.reason=error policy requested retry

And this in the restate pod (also here I'm not sure why it tries to use port 9080, because the container port is 8080):

I'm registering the CRD like this:

...
  restate:
    register:
      cluster: restate
....

Update: I made it work with this: #52

Thanks a lot for looking into the problem and fixing it @krisztiansala 🙏 We'll take a look asap.

Fix is in 1.8.1

I also had to add this parameter, otherwise it was still not working correctly with the custom service path:
